The concept of the 'Anthropocene' has gained significant traction in geological and environmental circles, positing that human activity has become a dominant force shaping Earth's systems. Proponents argue that markers such as nuclear fallout, plastic pollution, and elevated carbon dioxide levels constitute a distinct stratigraphic signature, warranting a new geological epoch. However, critics within the geological community contend that the term lacks formal precision, as these markers are not globally synchronous and may not persist over geological timescales. They suggest that the Anthropocene is more aptly described as an ongoing historical event rather than a formal chronostratigraphic unit. This debate underscores a fundamental tension between the need for scientific rigor and the desire to highlight humanity's profound and lasting impact on the planet.
❓ Согласно тексту, какова основная причина, по которой некоторые геологи выступают против официального определения антропоцена как новой геологической эпохи?
A. Маркеры человеческой деятельности слишком незаметны, чтобы их можно было обнаружить в горных породах.
B. Предложенные маркеры не являются глобально согласованными и могут не сохраняться на протяжении длительных геологических периодов.
C. Эта концепция продвигалась только экологами, а не геологами.
D. Влияние человека на Землю слишком недавнее, чтобы его можно было изучать научно.
✅ 正确答案
The proposed markers are not globally consistent and may not endure over long geological periods.
